There push factors and pull factors in the larger Chinese interior and the coastal region respectively. Migration can have negative effects in both the origin and the destination. Other economic activities like farming and industrial development can negatively be affected in the origin while the destinations experience a rapid population growth that is more than the economic growth and/or supply of services by the government, hence the need to control the migration. The side effects of this controlled migration can be slower rate of growth in the coastal region due to lower number of investors from the other parts of china.
My family moved from the rural setup to a town setup. The rural area was too harsh in terms of water supply, electricity, good schools among others. The pull factor was the good facilities available in the town as entertainment, schools, infrastructure, and others.
Rural-urban migration in developed countries has the push factors like few entertainment places, wages, and infrastructure found in the rural areas. The pull factors are the numerous entertainment facilities, infrastructure and higher wages in the urban centres. The congestion and pollution in the urban areas also push people to move to the quitter and less polluted rural areas.
Scale is used to accurately present the data on migration. The scale can also be used to predict the trend in migration in the near future. Scales also show the population densities and differences in the region of origin and the destinations.
